突发特讯！马斯克SpaceX正式通告全球：宣布进行史上最大卫星降轨行动，罕见措辞引爆国际舆论

Core Viewpoint - SpaceX's plan to lower approximately 4,400 Starlink satellites from 550 km to 480 km is primarily aimed at enhancing space safety and reducing collision risks, but it also reflects the challenges posed by natural phenomena and the need for strategic adjustments in the competitive landscape of space operations [1][4]. Group 1: Reasons for the Orbital Adjustment - The official reason for the orbital adjustment is to alleviate space congestion, as the number of Starlink satellites has exceeded 9,300 and is expected to surpass 10,000 soon [3]. - The real impetus behind this decision is the alarming increase in satellite re-entries, with 316 satellites expected to fall in 2024 alone, and a record of over 120 satellites re-entering in a single month in 2025 [3][4]. - The heightened activity of the sun is causing unexpected atmospheric drag on low-orbit satellites, leading to accelerated orbital decay and premature satellite retirement [3][4]. Group 2: Strategic Shift in Space Competition - The large-scale orbital adjustment signifies a shift in the global low-Earth orbit satellite internet competition from aggressive expansion to a focus on operational efficiency and risk management [6][7]. - The previous phase was characterized by rapid growth and competition for orbital resources, but increasing congestion has raised operational costs and collision risks, prompting a need for regulatory frameworks [6][7]. - SpaceX's strategy now emphasizes optimizing satellite configurations and enhancing controlled deorbiting capabilities to maintain its competitive edge while ensuring safety and compliance [7]. Group 3: Diverging Governance Models - Concurrently, China's "Star Eye" project aims to launch 156 satellites for space traffic management, contrasting with SpaceX's focus on commercial interests and risk control [8][9]. - The differing approaches highlight a tension between private sector initiatives driven by profit and public infrastructure projects aimed at maintaining order in shared space [8][9]. - The future interaction between these two models will significantly impact the management of space debris and the prevention of catastrophic scenarios like the Kessler Syndrome [8][9]. Conclusion - SpaceX's satellite descent is a calculated response to both natural forces and governance pressures, temporarily mitigating immediate risks while raising fundamental questions about space sovereignty, resource allocation, and environmental protection [11]. - The ongoing developments in space operations underscore the need for a responsible and sustainable order in the increasingly complex domain of near-Earth space [11].
